Abstract
The utility model discloses a close impeller structure on fan, include relevant fan casing, close the impeller of installing in the fan casing, its characterized in that: the impeller medial surface add one deck silica gel pad on the surface, the silica gel pad through the bolt erection joint on the impeller, the silica gel pad upwards extend and exceed in the top surface of impeller, silica gel pad and impeller connection form the soft or hard association. The utility model discloses the soft silica gel pad that utilizes the installation has reduced the wearing and tearing of impeller with pass fan inner wall, and the heat of also reducing friction and producing has prolonged the life who closes the fan, also guarantees sealed dust removal effect.
Description
Technical field
The utility model relates to the technical field of Blowing stopper, the blade wheel structure mainly on a kind of Blowing stopper.
Background technology
Blowing stopper is for installing the discharge gate place of the discharger worked under negative pressure, top accepts the material that discharger is discharged, and relies on the impeller rotated to play a part convey materials, is responsible for again the effect of sealing, prevent from sucking air from discharge gate in process of pneumatic transmission, ensure the normal discharge of discharger.In the knee-piece production process of liquor industry, the material in storehouse draws off also to feed in next device continuous uniform and goes by its dependence Action of Gravity Field of material and the positive action of feeder operating mechanism.The Blowing stopper that our brewery adopts is primarily of housing, impeller and end cap composition, rotated by shaft coupling impeller by reducing motor during work, the material of housing upper is evenly taken to bottom by next device, material is seen off, bearing and reductor are all outwardly, and dust can be avoided to get into bearing and large granular materials stuck phenomenon.In actual production, there is several places weak point in this Blowing stopper: 1 in technological requirement: Blowing stopper impeller and housing are rigidity.During operation, along with enter impeller and the housing of material produce friction, cause damage in impeller, and then cause impeller and body clearance to strengthen, sealing effectiveness is poor, dust removing effects reduction.2: the friction between impeller and housing, cause impeller longitudinal size to reduce, shell intracorporeal space strengthens, so single replacing impeller can not solve Blowing stopper sealing dust removing effects, integral replacing, economic input is large.
Utility model content
Technical problem to be solved in the utility model is to provide the blade wheel structure on a kind of Blowing stopper, its structural development is simple practical, the soft silicagel pad of installing is utilized to reduce the wearing and tearing of impeller and Blowing stopper inwall, also fricative heat is reduced, extend the service life of Blowing stopper, also ensure sealing dust removing effects.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Blade wheel structure on a kind of Blowing stopper, include the impeller installed in Blowing stopper housing, Blowing stopper housing, it is characterized in that: the surface of described impeller medial surface has additional one deck silicagel pad, described silicagel pad is installed by bolt and is connected on impeller, and described silicagel pad upwards extends above the end face in impeller; Described silicagel pad and impeller are connected to form soft or hard combination.
Blade wheel structure on described a kind of Blowing stopper, is characterized in that: described silicagel pad thickness is 2-3m.
On the surface of Blowing stopper impeller medial surface, add one deck silicagel pad in the utility model, form soft or hard combination,
The rigid impeller stayed ensures blanking, and soft silicagel pad reduces the wearing and tearing of impeller and Blowing stopper inwall, reduces fricative heat, ensures sealing dust removing effects simultaneously.Silicagel pad need be changed for daily can ensure to seal dust removing effects.
The utility model has the advantages that:
The utility model structural development is simple practical, utilizes the soft silicagel pad of installing to reduce the wearing and tearing of impeller and Blowing stopper inwall, also reduces fricative heat, extend the service life of Blowing stopper, also ensures sealing dust removing effects.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of I in the utility model.
Detailed description of the invention
See Fig. 1, blade wheel structure on a kind of Blowing stopper, include the impeller 2 installed in Blowing stopper housing 1, Blowing stopper housing 1, the surface of described impeller 2 medial surface has additional one deck silicagel pad 3, described silicagel pad 3 is installed by bolt 4 and is connected on impeller 2, and described silicagel pad 3 upwards extends above the end face in impeller 2; Described silicagel pad 3 is connected to form soft or hard combination with impeller 2.
Described silicagel pad 2 thickness is 2-3m.
Claims (2)
